METALLIC. WHEEL-HUB.

SPECIFICATION forming part of Letters Patent No. 693,347, dated February 1 1, 1902.

Application filed January 28, 1901. Serial No, 45,099. (No model.)

To aZZ whom it may concern:

Be it known that I,WILLIAM H. CULLERs, S12, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in MetallicWheel-Hubs, of which the followingis a specification.

This invention relates to certain new and useful improvements in metallic wheel-hubs adapted particularly for securing the spokes of. a wheel in position. i

The invention aims to construct a metallic wheel-hub of malleable iron or other suitable metallic material having cast integral therewith a series of radially-extending stems or projections upon which the metal spokes are fitted over and permanently secured. The spokes may be made hollow their entire length or recessed at one end, and, further, may be of any desired shape. The hub carries a pair of grooved retaining-collars secured together by suitable means and which fit over the ends of the spokes when mounted upon the stems or projections, materially assisting in retaining the same in position; and to this end the invention further aims to construct a metallic wheel-hub which shall be extremely simple in its construction, strong, durable, and efficient in its use, and comparatively inexpensive to,

manufacture.

The invention further consists in the novel combination and arrangement of parts hereinafter more specifically described, illustrated in the accompanying'drawings, and particularly pointed out in the claims hereunto appended, and in describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, wherein like numerals of reference indicate corresponding parts throughout the several views, and in which- Figure 1 is a perspective view of my metallic vehicle-hub with the spokes attached to the stems or projections and the retainingcollars in position, the spokes being broken away. Fig. 2 is a longitudinal section. Fig. 3 is a vertical section. Fig. 4 is an elevation of the hub with a modified form of stems or projections.

Referring to the drawings by reference-numerals, 1 represents an annular metallic hub formed in one piece, with a series of radiallyextending stems or projections 2 cast integral therewith,which taper outwardlyand are substantially oblon gin cross-section. The stems or projections 2 as shown in longitudinal section are larger at the bottom than at the top and in vertical section larger at the top than the bottom and are adapted to have fitted thereon the hollow metal spokes 3. By forming the stems so that the perimeter thereof will equal the inner perimeter of the spokes 3 the latter can be driven on the stems and secured to the latter, and it will be evident sired, in any suitable manner, such as welding, accomplished by heating the parts in a suitable manner and subjecting them to pres sure or to blows under proper conditions, such as known to those skilled in the art, or the spokes when heated driven upon the stem, causing the spokes to be secured thereto.

Mounted upon the hub at each side of the stems or projections 2 is a retaining-collar 4, its inner edge 5 conforming to the shape of the hub. The retaining-collars on their in nor face are provided with a series of cor responding grooves 6, in which are seated the stems or projections 2. The grooves 6 when registering with each other are substantially the same shape as the stems or projections 2. The collars 4 are further provided with a series of corresponding openings 7, through which extend the fasteningbolts 8, carrying the nuts 9. These bolts and nuts are adapted to secure the collars t together, so that the inner facesthereof will engage each other and retain the spokes within the grooves of the collars when the spokes are fitted or otherwise secured to the stems or projections.

In the arrangement shown in Fig. t the hub l is provided with a series of integral radially-extending projections 10, (only one shown,) formed with a shoulder 11. The projections are formed substantially tapering and have their inner portion 12 contracted, so as to form the shoulder 11. The inner portion 12 of the projections is of greater breadth and less height than the outer portion 13 thereof. WVhen the spokes are driven or mounted upon the projections, they are drawn in under the shoulder 11, thereby securely holding them in position. The retaining-collars 4 may be dispensed with, if desired, when using the form of stem or projection shown in Fig. 4, although it is not essential, as the collars 4 will always materially assist in retaining the spokes in position, as they will always prevent a lateral motion and act upon any movement along the axis of the spoke when used either with the stems or projections 2 or the stems or projections 10.

It is thought the many advantages of constructing a hub in the manner set forth and providing the same with the retaining-collars can be readily understood from the foregoing description, taken in connection with the accompanying drawings, and that one of the distinguishing features thereof is the fact that the stems or projections on the hub are fitted within or secured to the spokes, thus avoiding the difficulties and objections which attend the introduction of the spokesinto mortised hubs or hub-sockets, and the retainingcollars for securing the spokes to the stems or projections.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. A metal wheel-hub having stems or projections formedintegra]. therewith upon which the wheel-spokes are fitted, and a pair of collars mounted upon the hub, each of which fits around a part of the spokes for securing them to the stems or projections.

2. A metal wheel-hub having stems or projections formed integral therewith upon which the wheel-spokes are fitted, and a pair of grooved collars mounted upon the hub for securing the spokes to the stems or projections.

3. A metal wheel-hub having stems or proj ections formed integral therewith upon which the wheel-spokes are fitted, a pair of collars mounted upon the hub for securing the spokes to the stems or projections, and means extending through the said collars for connecting them together.

4:. A metal wheel-hub havingstcms or projections formed integral therewith upon which the wheel-spokes are fitted, a pair of collars, each of which is grooved on the inner face and surrounding said spokes forsecuring the latter to said stems or projections, and means for connecting said collars together.

In testimony whereof I have hereunto set my hand in presence of two'subscribing witnesses.
